Lame facebook question

My facebook status used to say "...at 6:40 via ANDROID." Now it stopped and says ..."via mobile" or the nearest city to me. How do I change it back to saying droid in the timestamp? I'm using the facebook for android app and never used the social network app that came with the phone. My D2G is all stock and never been rooted or anything else. I know its a lame question, but you guys are the experts.
